The answer, before the detail
Expect filter housing seated wrongly after a change before anything else. An icemaker is a simple machine with three demanding inputs, and this ranking is ordered by which of those inputs fails most often on a cabinet of this kind.
What the refrigerator is actually doing
- Ice production is slower than it used to be but has not stopped — A partly restricted supply or a marginal freezer temperature shows up as a rate change first.
- The icemaker filled once and then stopped — A frozen fill tube behaves exactly like this: one good cycle, then a block of ice in the way.
- A single slab of fused ice in the bin — Cubes that melted slightly and refroze together mean the freezer has been warm at some point.
- NEAR MISS — the dispenser will not dispense but the bin is full — Ice being made but not delivered is a dispenser or auger problem, and that is a different fault from production.
The ranking, and why it is this way round
- Filter housing seated wrongly after a change — A filter restricts gradually as it loads, and the icemaker notices before anyone else does because it fills against a timer rather than against a thumb on a lever. Ranked ahead of the rest since it is both the likeliest and the only one that can be settled before anything is taken apart. With a badge of this size the sensible order is the one that gets you to an answer without waiting on a part that may take weeks to arrive.
- Water supply shut off, kinked or frozen at the fill tube — A line pinched by the cabinet being pushed back against it is one of the most common causes of this complaint, and it appears at exactly the moment nobody associates with the icemaker: after a clean behind the fridge. Second, because it produces the same complaint from the other side and is still an owner-side check.
- A freezer running warm, so the mould never releases — An icemaker does not make ice on a timer alone: it waits until the mould itself is cold enough, then harvests. A freezer running a few degrees warm will produce ice slowly, or stop altogether, while still keeping food frozen. It ranks here because it is genuinely less common, not because it matters less when it happens.
- The assembly itself, electrically failed — The fill valve is the most likely of the three because it is the only one exposed to water and to line pressure, and it is usually reached from the back of the cabinet rather than from inside the freezer. Last, and the reason the order matters: it is the least likely of the four, and the three above are quicker to settle.
Check in this order, and why
- Remove and refit the filter, checking it seats and locks properly — A quarter turn short of home is enough to restrict flow without leaking a drop. First, because it separates the top two causes in under a minute.
- Trace the water line to the shutoff and check it is open and not kinked — Do this before anything else — it is the single most common reason an icemaker stops. Next: it confirms or clears the cause ranked second, and needs nothing but light.
- Check the freezer door seals and that nothing holds the door open — A door held ajar by a box is the commonest reason a freezer runs warm without anything failing. Third: by now the answer is usually already in hand.
What you can do yourself
- Change the water filter, then run water through the dispenser until it is clear — Expect trapped air to splutter for a while after a change; that is normal and settles.
Tools: replacement filterAbout 20 min
- Thaw the fill tube with the icemaker switched off — Let it melt on its own or with warm water on a cloth; never chip at it with anything hard.
Tools: cloth, warm waterAbout 45 min
- Measure the freezer temperature properly, between packages rather than in the door — Leave the thermometer in place for several hours rather than reading it immediately.
Tools: thermometerAbout 30 min
- STOP if a step would mean defeating an interlock or a safety switch — Those exist to stop the appliance running in a state that can hurt someone. There is no version of this job worth bypassing one.
Before you touch anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. If you smell burning, stop there and call — do not keep running it to see whether the smell returns. Work with dry hands on a dry floor, and never chip at frost with a tool that can puncture tubing.
When this becomes a service call
Book sooner if water is escaping anywhere: a leak outranks lost ice, and an overfilling valve explains both complaints at once.

A note on scope: this page treats Kova refrigerators as one class. A page written for your specific family or model line will carry what this one deliberately leaves out — component locations, fastener sizes and the disassembly order — and it takes precedence over this page for your unit.
